The popping sound (kind of like a "bang" out of no where) isn't necessarily related to a leak. We had the popping sounds from day 1 with our 385TH. One bottle of CAT fluid, and the issue was resolved. It's never happened again.

We just noted that two of the jacks are leaking a little. Both are on the same side. That's just under 5 years later.
